专利汇可以提供Halogen type filament lamp containing phosphorus and nitrogen专利检索，专利查询，专利分析的服务。并且A tungsten-halogen cycle electric incandescent lamp has a fill including a phosphonitrilic halide. Mixtures of more than one of the halides may be employed. The halide can be introduced into the lamp envelope in solution, the solvent being evaporated thereafter to leave the halide as a residue.，下面是Halogen type filament lamp containing phosphorus and nitrogen专利的具体信息内容。
1. An electric incandescent lamp comprising: a closed light-transmitting envelope of a high temperature-resisting material; electrically-conducting lead-in wires sealed through said envelope; a tungsten filament inside said envelope connected to said lead-in wires; and a fill inside said envelope comprising an inert gas and the products resulting from the thermal dissociation of a phosphonitrilic halide comprising (PNY2)n, where n is an integer and Y is Br or Cl, said fill thereby releasing a predetermined amount of said Br or Cl to produce a regenerative cycle and releasing a predetermined amount of said P to produce a gettering action and to inhibit the reaction of said Br and Cl with said tungsten filament.
2. A lamp according to claim 1 wherein said phosphonitrilic halide includes a mixture of (PNBr2)3 and (PNBr2)4.
3. A lamp according to claim 1 wherein said phosphonitrilic halide includes a mixture of (PNCl2)4, (PNCl2)5, (PNCl2)6, and (PNCl2)7.
4. AN ELECTRIC INCANDESCENT LAMP COMPRISING A CLOSED LIGHT TRANSMITTING ENVELOPE OF A HIGH TEMPERATURE-RESISTING MATERIAL, ELECTRICALLY-CONDUCTING LEAD-IN-WIRES SEALED THROUGH SAID ENVELOPE, A TUNGSTEN FILAMENT INSIDE SAID ENVELOPE CONNECTED TO SAID LEAD-IN WIRES, AND A FILL COMPRISING AN INERT GAS AND NITROGEN, PHOSPHORUS AND A HALOGEN, SAID NITROGEN, PHOSPHORUS AND HALOGEN HAVING BEING FORMED BY THERMAL DISSOCIATON OF A PHOSPHONITRILLIC HALIDE.
